It was a global conflict that started in Europe in 1914 and ended in 1918. It was a bloody confrontation in a continent that had planet's domination. So, the leading forces in Europe offered a massive cruelty and destruction scene. A continent filled with dead bodies and anger meant the end of the European leading.

The conflict's sources are in the market, colonial, and politic differences that splitted the European leaders. France was in favor to the revenge against Germany: France pretended to recover Alsacia-Lorena territory. Russia and Austria were in conflict in “The Balkans”, where the slavish people were rejected and they were a reason of rage against Vienna and some wish to obtain Moscow's help. Great Britain and Germany were centered in a heavy industrial, commercial and sea competition. Russia moved by their need to get the Middle Sea pretended to split Turkey but they found a heavy opposition by France and Austria. In their desire to find the Pacific Ocean were in conflict USA and Japan.

All these conflicts unchained a lot of rage that started a growing weapons race. By the circumstances, the only way to stay in peace was in the use of the weapons.

There were two bands, the Triple Alliance that were Germany, Austria and Hungary, and the others, the Triple Entente that were Great Britain, France and Russia.

STARTING AND DEVELOPEMENT OF THE CONFLICT:

The immediate cause of the war between Austria-Hungary and Serbia was the assassination on June 28, 1914, at Sarajevo in Bosnia (then part of the Austro-Hungarian Empire; now in Bosnia and Herzegovina), of Archduke Francis Ferdinand, heir presumptive to the Austrian and Hungarian thrones, by Gavrilo Princip, a Serb nationalist. The fundamental causes of the conflict, however, were rooted deeply in the European history of the previous century, particularly in the political and economic policies that prevailed on the Continent after 1871, the year that marked the emergence of Germany as a great world power.

After the assassination of Ferdinand and Sophia, his wife, Austria sends an ultimatum to Belgrade that was rejected by Serbia. Because of that, Austria starts a troupe movement attacking Serbia. After that, Russia attacks Austria and then Germany. Then, Germany falls over Belgium to attack France but the Germans were stopped in the Marne River by the Fosch Captain. Finally, Germany takes advantage over Russia, recovering their territory and obtaining Russian territory. This is the First World War's phase known as THE MOVEMENT WAR. The second war's phase is known as TREACHERY WAR. In this phase, soldiers stayed inside uncomfortable “holes” where they were affected by pests, hungry, and mental transformations. This war was known as a LOSING WAR because none of the bands took advantage and the soldiers died because of the diseases waiting for the other band's attacks. The soldiers stayed for long periods of time like months and years inside those “holes”.

The decisive fact that ended the war was the USA entering to the war because a German submarine sunk an American ship, the so-called Lusitania. There were a lot of American passengers and some English Lords. After that, USA joined the war in favor to the Triple Entente and soon the situation was in favor to the Triple Entente. Finally, the Triple Entente defeats the Triple Alliance in 1918. After defeating the Triple Alliance, every winning countries' diplomats met in a reunion to decide what was supposed to happen after the war, so, they signed the Versalles treat. This treat established that:

1.- Germany was the war starter

2.- Germany had to pay an indemnization near $33.000.000.000

3.- Germany had to give Alsacia-Lorena territory to France and the Sarre territory.

4.- Germany must have a limited number of troupes.

5.- Germany had to deliver all their colonial territories.

6.- It is recognized the Polish independence and it is given to them an exit to the Baltic Sea, so, Germany is splitted in two. The exit is known as the Danzig corridor.

So, the ending of the war gives to Germany a lot of disgusting conditions and they were reduced to the oppression of the winning countries. But later, Germany will recover and will follow up their past steps and will be a world power again with the help of Adolf Hitler and a lot of external facts. But Germany will be defeated again and a new process is initiated for Germany, their freedom proccess that ends in 1990 with the Berlin Wall's fall.
